Movement by [[Hublot]]

[[Self-winding]] [[chronograph]] movement.

This calibre evolved out of the collaboration of Hublot with [[La Joux-Perret]] as a further development of the famous [[Valjoux 7750]], the most popular contemporary chronograph calibre.

One notable addition to later versions of the HUB 44 (or La Joux-Perret 8144) is its use of a [[column wheel]] rather than the cam-based chronograph system of the donor movement. La Joux-Perret produced similar column wheel 7750 movements for [[Graham]], [[Chopard]], [[Corum]], and [[Eberhard]]. [[Alfred Rochat]] also produced a column wheel variant of the 7750 for [[Chronoswiss]], as did [[ETA]] themselves for [[Longines]].

Characteristical difference to the 7750 is the implementation of the [[rotor]], which is manufactured in [[tungsten]] carbide and is [[skeletonized]].
